Study summary

What the protocol is testing.

In this prospective, randomized, double blind study, the aim is to determine the efficacy of Linaclotide in relation to Senna in relieving the symptoms of chronic idiopathic constipation (CIC). Patients with CIC, (age 18 - 70) will be enrolled in the study and randomized to Senna or Linaclotide. Patients will be asked to complete questionnaires during the study and will be followed for 12 weeks. Main outcomes include number of daily bowel movements and measures from surveys regarding bowel habits, relief, and satisfaction.

Full detailed description

In this prospective, randomized, double blind study, the aim is to determine the efficacy of Linaclotide in relation to Senna in relieving the symptoms of chronic idiopathic constipation (CIC). Our hypothesis is that Senna is not inferior to Linaclotide in the treatment of CIC. Seventy patients aged 18-70 diagnosed with CIC and seen by a gastroenterologist affiliated with TriHealth or a patient of the Faculty Medical Center clinic will be included in the study. After enrollment, subjects will be randomized to receive either Linaclotide or Senna over a 12-week period after a 1 week wash-out period. During th study period, subjects will complete a log to record the number of daily bowel movements. The subjects will also complete 3 validated surveys on a weekly basis: Subject's Global Assessment SGA of Relief, Subject's Global Assessment SGA of Bowel Habit, and SGA of Satisfaction with their Bowel Habit. A research nurse will meet with subjects at the beginning of the study and then at 3 monthly visits to administer the study medication and distribute the surveys. The main outcomes measures are change in # of bowel movements and SGA survey scores.

Outcomes

What the study measures.

Primary outcomes

Change in Number of Bowel Movements Per Week

Time frame · 12 weeks

Change from before to after in number of weekly bowel movements

Secondary outcomes

Number of Participants With Relief

Time frame · 12 weeks

Change from before to after treatment in patient assessment of relief - The Subject's Global Assessment (SGA) of Relief was used to measure this outcome. In evaluating subject's response to SGA of relief, subject's who respond with either "completely relieved" or "considerably relieved" for at least 50% of the weeks at the end point or "somewhat relieved" for 100 % of the weeks at the end point will be considered responders to therapy.

Change in Assessment of Bowel Habit

Time frame · 12 weeks

Change from before treatment to after treatment in assessment of bowel habit The Subject's Global Assessment (SGA) of Bowel Habit was used to measure this outcome. Patients were asked how bothersome their constipation was in the past week on a scare from 0 (Absent) to 100 (Very Severe).

Change in Satisfaction With Bowel Habit

Time frame · 12 weeks

Change from before treatment to after treatment on patient satisfaction with bowel habit The Subject's Global Assessment (SGA) of Satisfaction with Bowel Habit was used to measure this outcome. Patients were asked how satisfied they have been with their bowel habits in the previous week on a scale of 0 (Unsatisfied) to 100 (Very Satisfied).
